The sample program uses the following memory locations:
Bit 00.00
= Bit to be set by the user when achannel is to be
configured.
Bit 1700.00 = Bit used to detect the rising edge of Bit 00.00.
Register 10 = Register contains the coils corresponding to the
status of the voltage input High High alarms
Register 11 = Register contains the coils corresponding to the
status of the voltage input High alarms
Register 12 = Register contains the coils corresponding to the
status of the voltage input Low alarms
Register 13 = Register contains the coils corresponding to the
status of the voltage input Low Low alarms
Register 1600= Internal coils
Register 160 = Internal coils
Register 1610= The register's bits are used to indicate the current
state of operation.
Bit .00 represents state 0 which writes the READY
command to the Voltage Input module and then
reads the module's configuration status. If the
complete bit of the configuration status register is
equal to zero, advance to state 1.
Bit .01 represents state 1 which reads channel
configuration data from the AutoMate's memory and
writes it out to the Voltage Input module. State 1
then reads the Voltage Input module's configuration
status. If the configuration is complete and there are
no errors, go to state 2.
Bit .02 represents state 2. This state directs the
program to continue with the configuration of the
next channel (state 0), provided no errors have
been detected.
Bit .16 is set when an error is detected and the
configure operation is aborted.
Bit .17 is set when all three of the voltage input
channels have been configured.
Register 1611= Register is loaded by the REMIN instruction which
contains the contents of the Configuration Status
Register (Register 22).
Register 3000= Register contains the pointer to the data that is to be
written to the Voltage Input module.
Register 3001= Register contains the voltage input channel number
that is being configured.
Register 3002= Register contains the voltage input channel's
Maximum Scaling Value. This value is provided by
the data table in the 5000Ćseries registers.
Register 3003= Register contains the voltage input channel's
Minimum Scaling Value. This value is provided by
the data table in the 5000Ćseries registers.
Register 3004= Register contains the voltage input channel's
Number of Samples. This value is provided by the
data table in the 5000Ćseries registers.
